STARTING DEVICE FOR ADJUSTABLE VAPOR APPARATU S.

sesame.

To all whom it may concern:

Be it known that I, PERCY H. THOMAS, a

. citizen of the United States, and resident of East Orange, county ofEssex, State of New Jersey, have invented certain ne 7 and usefulImprovements 1n Startmg Devices tor Adjustable Vapor Apparatus, of whichthe fol tions, either horizontally or vertically or inclined. Moreover,it is the practice with some types of such apparatus to perform the actof starting by bringing about a momentary contact between the mainnegative electrode and a supplemental positive electrode, the startingof theapparatus taking place when this contact is interrupted. Afamiliar form of the apparatus is one in which the main negativeelectrode is of mercury and the supplemental positive electrode is ofsome solid conductingmaterial. Heretofore, however, the matter ofproviding for the easy starting of such apparatus in any position whichit is contemplated that it should'occupy has been overlooked.

T he present invention provides conven ient means for startimg theapparatus whether it is located at the time of starting in a horizontalposition or in any other position in which it is likely to be used.

The main feature of the invention consists in so locating thesupplemental electrode that it is within'operating distance of the mainelectrode at all times, whatever position'ot the app: 'atus.

The invention will he clearly understood Specification of LettersPatent.

ltn the drawings, 1 is the container of a. mercury vapor apparatus, 2 isan electrode of iron or other suitable material, and 3 is the mainnegative electrode of mercury.

At 4 I locate a supplemental positive electrode which is so located asto be near the 1 mercury of the negative electrode inevcry position ofthe apparatus. To start the apparatus into operation, it is onlynecessary to jar the mercury of the negative electrode into contact withthe supplemental elec- 'trode 4, after which, on the return of themercury by gravity to its operating position, the current will flowthrough the ap paratus between the main ositive electrode- 2 and thenegative electro e 3. The apparatus shown in Fig. 1 may bepivoted upontrunnions, one of which is shown at 5' supported in clamp bearing 6, andmay be turned to a vertical, horizontal or inclined position at the Willof the operator. The converterillustrated in Fig. 2 may also be turnedupontrunnions and may occupy a. variety of positions without removingthe mercury so far from the supplemental electrode 4 as to be beyondeasy striking distance.

I claim as my invention In a vacuum electric apparatus including anexhausted container, and electrodes therefor, including a cathode, thecombination withsupporting means adapted to permit the movement of saidcontainer into and to support said container in vertical, horizolr taland intermediate positions, of a supplementary anode adapted tocooperate with said cathode in all of said positions.

Signed at New lork, in the county of New York, and State of New York,this 6th day of April A. D. 190%.
